Our Billet Water Filler Necks are machined with either a -12AN or -16AN female straight o-ring port in the front.  This allows for use of the size fitting of choice for your application.  Fittings are sold separately for this reason. -08, -10, -12 AN fittings are available or fittings to fit your 1.25, 1.50 and 1.75 radiator hoses.

Our Billet one-piece designed top expansion portion is unique to the industry and bolts to the base plate with an o-ring seal by 4 provided stainless steel cap screws.  1/4" push lock overflow fitting also provided.

Racers ourselves, We spent a tremendous amount of time making sure of the fit for the radiator cap, insuring the pressue seal and locking mechanism work as well as possible for extreme racing conditions.
